Description

Technical Field

[0001] The utility model relates to the technical field of traffic guardrails, in particular to an anti-collision device for traffic guardrails. Background Art

[0002] Among existing transportation infrastructure, traffic guardrails are widely used in roads, highways, bridges, tunnels, and other locations. Their primary function is to prevent vehicles from running out of control, ensuring driving safety and maintaining traffic order. These guardrails are typically made of metal or plastic materials, possessing a certain degree of rigidity and strength to withstand vehicle impacts.

[0003] However, traditional traffic guardrails present significant challenges when responding to vehicle impacts. Due to the guardrail's rigid structure, the impact energy often cannot be effectively absorbed, resulting in significant impact force on the vehicle and passengers, which can easily cause damage. Furthermore, the guardrail itself can be severely damaged by the impact, even breaking or deforming, rendering it unable to provide its intended protective function.

[0004] Therefore, those skilled in the art have proposed an anti-collision device for a traffic guardrail to solve the problems raised in the background art. Summary of the Invention
